Electronically Reconfigurable Varactor-Loaded HMSIW Bandpass Filter

, 2018
A varactor-loaded half-mode substrate integrated waveguide (HMSIW) reconfigurable bandpass filter (BPF) is proposed in this paper. The proposed BPF is composed of complementary split-ring resonators (CSRRs) and varactors. Meanwhile, a nonmetalized via is

Anisotropic Second‐ and Third‐Harmonic Hermite–Gaussian Beam Generation with NbOI2 Holograms

Advanced Photonics Research, Volume 6, Issue 12, December 2025.
Anisotropic second‐ and third‐harmonic Hermite–Gaussian (HG) beam generation is demonstrated with ultrathin NbOI2 grating holograms to produce the nonlinear HG01 and HG10 modes with high anisotropy ratios. The relative magnitudes of the second‐ and third‐order nonlinear susceptibility tensor elements of NbOI2 crystal are extracted. These demonstrations

Wideband bandpass filter for MB-OFDM application

, 2012
[[abstract]]This article presents a wideband bandpass filter (BPF) designed using novel multimode resonators (MMRs). The MMR is formed by combining two quarter-wavelength (λ/4) stepped-impedance resonators (SIRs) in a structure-shared fashion.

Laser Ultrasound Super‐Resolution Imaging for Multi‐Parametric Non‐Invasive Volumetric Characterization of Brain Cancer

Advanced Science, Volume 12, Issue 47, December 18, 2025.
Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.

Design of a new bandpass filter using anti-Parallel coupled asymmetric SIRs

, 2012
[[abstract]]In this paper a newly designed internally-coupled asymmetric stepped-impedance resonator (SIR) bandpass filter (BPF) is proposed. The asymmetric SIR structure not only can effectively reduce the circuit size but also can provide two flexibly ...

A Compact Dual Bandpass Filter Using Dual Composite Right-/Left-Handed and Open-Loop Ring Resonators for 4G and 5G Applications [PDF]

Radioengineering
In this paper a very compact design of a dual-band band pass filter (D-BPF) using dual composite right-/left-handed (D-CRLH) and open-loop ring (OLR) resonators is presented. To overcome the frequency ratio limitations of D-CLRH resonators technique, the

Novel design and implementation of 3d packaged wideband bandpass filters

Scientific Reports
This study presents an innovative method for designing a 3D packaged wideband bandpass filter (BPF) by vertically integrating a high-pass filter (HPF) and a low-pass filter (LPF) using an air cavity and vertical interconnect accesses (VIAs).

Monolithically-Integrated Bandpass Filters Using Capacitively-Loaded Intertwined Helical Resonators

IEEE Journal of Microwaves
This paper presents a novel compact 3D bandpass filter (BPF) concept based on new classes of intertwined helical resonators. The concept is demonstrated by three unique RF filter architectures: a second-order single-band BPF, a second-order dual-band BPF,
